Basic Network VLAN and Subnet Architecture Advice, Please

We are looking at redesigning our network core with some new VLANs and subnets. (something much easier to manage than what we have now). I'm looking for some guidance, or at least a 'thumb's up' on what we're doing. Thanks!

Current Plan:

VLAN 100 - 172.16.100.0/22
Desktops, laptops, smartphones, end user devices, etc.

VLAN 110 - 172.16.110.0/23
VDI machines

VLAN 120 - 172.16.120.0/24
VoIP Phones

VLAN 130 - 172.16.130.0/24
VM Servers, ESXi hosts, SANs

VLAN 140 - 172.16.140.0/24
Network devices, switches, routers, etc.

VLAN 150 - 172.16.150.0/24
Printers

Note: This is a fiber channel network, so the hosts and SANs will have a couple FC and several gigabit NICs.

Is this a decent plan?
Do you think there is an issue with putting ESXi hosts and SANs in the same VLAN/subnet as VM servers?
Should printers and end user devices be split up?

Any other thoughts or advice are welcomed.

What is the benefit to separating the hosts/sans from the servers?

I do have one set aside for vmotion. Just didn't list it. Good eye, though.

/22 and /23 are because I will need more than 254 IP's for each respective subnet.
